2357 can be expressed as the repdigit sum of its (prime)
digits: 2222 + 3 + 55 + 77. Note that the latter summands
concatenate, in some appropriate order, into a prime, in
three different ways all starting with "55": 553222277,
552222773, 557722223. [Beedassy]

The reverse concatenation of the two prime derangements
(5273 and 7523) of 2357 is prime: 75235273. Note that
sandwiching the latter between two blocks of prime 2357,
followed by halving at the middle yields a new pair of
primes (23577523 ; 52732357 ) both remaining prime when
every digit is replaced by its respective complement
(87533587 ; 58378753). [Beedassy]

Replacing from the left the first digits in 2357 by their partial sums forms a succession of four primes,viz., 2357, 557, 107, 17. Note that the reversals of both semiprimes 2357*557 and 107*17 are prime (9482131, 9181). [Beedassy]

The sum of the cubes of the first four Fibonacci primes.
Curiously, the prime contains three of them. [Silva]
